It looks close to a badger claw - but not the same. It doesn't have the high arch on the top side and hooks more at the end than gradually like the badger claw. As for size, I think it would match, but for shape it doesn't. I think it's something else. Young bear maybe? Not really sure. I don't think it's a tooth though. Some kind of non-retractable claw. Wolverine maybe?
